Which statement best defines Quality Control?

• A. It is the prevention of defects through process design
• B. It is the selection of suppliers based on quality records
• C. It is the training of employees in quality methods
• D. It is the checking and reviewing of work that has been completed to verify conformity

Answer: (D)

Quality control focuses on verifying that the finished work conforms to required standards. It’s about checking and testing what has already been produced to catch defects and confirm conformity before the product or service is delivered. This is a reactive activity, done after work is completed, to ensure outputs meet specifications.

The other ideas describe preventive or broader quality management activities. Designing processes to prevent defects, selecting suppliers based on quality records, and training employees in quality methods aim to build quality into the process (quality assurance) rather than inspect the final output.
